%% OTP-19 and OTP-21, where Unicode support means the deprecation
%% of a lot of string functions.

%% string:join/2 copy; string:join/2 is getting obsoleted
%% and replaced by lists:join/2, but lists:join/2 is too new
%% for version support (only appeared in 19.0) so it cannot be
%% used. Instead we just adopt join/2 locally and hope it works
%% for most unicode use cases anyway.
